SPECIFICATIONS

■ Sensor head

*1 Reference distance

Small: 65 mm, medium: 60 mm, large: 50 mm

*2 Large spot: 15 ± 5 mm, small spot: 15 ± 3 mm

*3 The focus distance is about 10 mm, but stable detection can be achieved

with 15 mm.

■ Ampliﬁer unit

*1 20 mA maximum when several units are connected.

When several units are connected, the acceptable ambient temperature var-

ies depending on the conditions given below. To connect several units, be

sure to mount them to a DIN rail. Ensure that the output current is 20 mA max.

When 1 to 2 units are connected: -10 to +50 °C

When 3 units are connected: -10 to +45 °C

MOUNTING THE SENSOR HEAD

■ Extraneous light

A detection error may occur when the light from high-frequency lighting equipment

such as an inverter ﬂuorescent lamp directly enters or reﬂected on the target into

the emitter. In such a case, apply a light shield plate or change the location of the

sensor

■ Target movement and sensor orientation

To stabilize the sensor output at a border, mount the sensor as shown in the

following ﬁgure as much as possible.

■ When using the CZ-H32

When detecting a metal surface or glossy target

When a target has a metal or glossy surface, the calibration/differentiation

may fail. To detect such a target, tilt the sensor head by approximately 10 to

15 degrees.

■ When using the CZ-H35S/CZ-H37S/H72

When a target has a glossy surface (a birefringence target such as an ori-

ented ﬁlm), the detection may fail depending on the mounting orientation. To

detect such a target, displace the sensor head by approximately 45 degrees.
